(a)

Interpretation Introduction

Interpretation: The formulas or names for the given molecular compounds are to be stated.

Concept Introduction : Molecular compounds are formed by the sharing of electrons between non-metals. They are known as carbon compounds. The naming of the compound is: $\text{Name}\text{of}\text{first}\text{element}+\text{Stem}\text{of}\text{second}\text{element}+\text{'}ide\text{'}$

Answer to Problem 32LC

The name of the compound is carbon disulfide.

Explanation of Solution

The given compound is ${\text{CS}}_{\text{2}}$ . It is composed of carbon and two sulphur atoms. The prefix used for ‘two’ is ‘di’. Thus, the name of the compound is carbon disulfide.
